The Porsche Panamera was originally introduced in 2009 but yesterday the German automakers unveiled the sportier Panamera GTS. The 2013 model dubbed the Gran Turismo Sport still utilizes a 4.8 liter V8 engine but horsepower got bumped up to 430 with 383 pounds of torque. Other notable specs are 0-60mph in 4.5 seconds with a top speed of 178mph. The super sedan now sits lower with upgraded suspension for better handling and beefed up brakes. The interior now has race inspired gauges and bucket seats as well. Basically, everything is sportier.

No word on pricing yet.
